MessageBox

Enabled: Constructs a new instance of this class given only its
parent.

Note: Currently, null can be passed in for the parent.
This has the effect of creating the dialog on the currently active
display if there is one. If there is no current display, the
dialog is created on a "default" display. Passing in null as
the parent is not considered to be good coding style,
and may not be supported in a future release of SWT.

Parameters:

parent - a shell which will be the parent of the new instance

MessageBox

Enabled: Constructs a new instance of this class given its parent
and a style value describing its behavior and appearance.

The style value is either one of the style constants defined in
class SWT which is applicable to instances of this
class, or must be built by bitwise OR'ing together
(that is, using the int "|" operator) two or more
of those SWT style constants. The class description
lists the style constants that are applicable to the class.
Style bits are also inherited from superclasses.

Note: Currently, null can be passed in for the parent.

display if there is one. If there is no current display, the
dialog is created on a "default" display. Passing in null as
